The thread of fate led them to meet and become congenial friends. However, the sparks caused by the collision of young minds also caused them to be temporarily separated and go their separate ways. As time goes by, the dragon gate of the imperial examination reunites them in the court. The young man of the past is now concerned about the country. They are not just for fame, but they join the current with a pure heart: inside the temple, they are determined to innovate and clean up the accumulated shortcomings; outside the border, they hold swords and armor to defend against powerful enemies. The ups and downs of officialdom, the light and shadow of swords, sharpened their wills and tempered each other's souls. This is the epic of a group of like-minded people who worked hard to write on the scroll of the times with their blood and wisdom, just to protect the peace and prosperity of thousands of lights behind them. Reunion is a resonance deep in the soul, and it is also the prelude to fighting side by side for all people in the world.
